1 Claim.

The object of this invention is to provide a novel ierrule for paintbrushes and the like, and, specically, to provide a ferrule theoverlapped portions of which are joined together by welding, preferablyby spot Welding.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the invention apupertains.

With the above and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, Without departing from the spirit of theinvention.

In the accompanying drawing:

Fig. 1 shows in elevation, a paint brush equipped with the ferruleforming the subject matter of this application;

Fig. 2 is a transverse section of the ferrule;

Fig. 3 is a longitudinal section of the ferrule;

Fig. 4 is an elevation of the ferrule.

Fig. 5 is an elevation showing a modified form of the invention, theedges of the ferrule being spaced apart;

Fig. 5 is a transverse section showing the edges of the ferrule of Fig.5 overlapped.

The numeral 1 marks a handle of a paint brush, the handle generallybeing made of wood and comprising an enlarged head 2, upon which thebody bristles 3 are held by a metal ferrule 4. The ferrule 4 hascircumferential, outwardly struck beads 5, and carries an inscription 6,generally of an advertising nature, and therefore represented in thepresent drawing by the legend Paint Brush. The ends of the ferrule 4 areoverlapped, as shown at 7, and are held together by spot welding,preferably located on the inside of the ferrule, and designated by thereference character 8.

In welding the ferrules, as hereinbefore described, the metal at thejoint is rendered as strong as any other part of the ferrule, and thestrength at the joint often is greater than else- Where.

The invention, therefore, places the device in a class with a seamlessferruie, but with an additional advantage which will now be alluded to.The bead lines shown in the drawing serve as a guide for setting thehandle and the bristles, but these beads cannot be made in a seamlessferrule. The same observation holds true with respect to the inscriptionshown at 6, since this inscription cannot be made in a satisfactory way,commercially, in a seamless ferrule. The bead lines and the letteringform, so far as manufacture and marketing are concerned, an essentialpart of a paint brush. It can be turned out readily in the deviceforming the subject matter of this application, but they are practicallyimpossible when a seamless ferrule is provided. The manufacturer of thegoods is entitled to the beads, to facilitate the manufacture andassembly of the brush, and the manufacturer or retailer is entitled tothe marking indicated generally by the Words shown at 6, in order toidentify the product.

Various expediente have been resorted to in the past, in an effort toturn out a ferrule for paint brushes, the ends of the ferrule beingbrought together and secured together. Butt ends have been suggested,connected together by solder, or otherwise, but a union which comprisesa butt end is unsatisfactory in a paint brush. Soldering processes,furthermore, have not afforded the desired strength, and have provenexpensive to manufacture. In the device forming the subject matter ofthis application, the spot Welding shown at 8 may be carried out withgreat rapidity, thereby cutting down the cost of the article, providinga ferrule which is equal in all respects to a, seamless ferrule, and, atthe same time, permitting beading and lettering, Which is something notpossible in a seamless ferrule.

In Figs. 5 and 6, the ferrule 10 has beads 11 as hereinbefore described.One end of the ferrule 10 marked by the numeral l2 is plain Whereas theother end of the ferrule, marked by the numeral 14 is provided with aline of bosses 15 struck from the end 14. of the ferrule. The end 12 isoverlapped on the end 14 and the parts are welded together ashereinbefore described.

The device shown in Figs. 5 and 6 is desirable especially when a lightgauge metal is used, and by providing the bosses l5, a more secure andpositive Weld is brought about than is possible otherwise.

Having thus described the invention, What is claimed is:

A ferrule for paint brushes, having inner and outer overlapped ends, theouter of said ends being plain, the inner of said ends having out-Wardly projecting bosses engaging the inner surface of the outer of saidends, the said ends being spot-Welded together at the bosses.
